I can’t write a correct editorial for this yet because the actual problem statement is missing. Right now I only know the title “Piggy Calculator”, but there is no description of what the calculator does, what inputs look like, or what needs to be computed.

CF 103118D - Dyson Box

I can’t reliably write a correct Codeforces editorial here because the problem statement is missing. “103118D - Dyson Box” isn’t included in your prompt, so anything I produce would be guesswork.
